The long awaited software is out. If you’ve not heard about it then you should have! The guys from Delicode; who brought us Ni-Mate have a brand new toy to play with. Enter Z-Vector…

“Z Vector is the world’s first professional visualization software based exclusively on modern depth sensors such as the Microsoft Kinect and the PrimeSense Carmine. It allows you to sample reality in real-time, visualize it the way you like and explore it in 3D with Full HD resolution. Create fresh material for your visual performances right there on the spot. Some great dancers in your crowd? Single them out from the background and make them part of your visual storyline. Assume control with our full MIDI/OSC support or mix Z Vector’s output with your existing set using Syphon (only on Mac OS X).”

I was lucky enough to meet Julius whilst I was in Helsinki for the LUX event and he gave me a sneak preview of it in action. I knew it was powerful then and its been 6 months (near enough to the day) now and wow it’s developed amazingly well.

I was lucky enough to get to test this amazing software well before the official beta test. I spent many hours playing around with parameters and creating some wonderful images. It’s been very hard to keep my mouth shut and even harder not to share any screenshots!!! I posted one or two that I knew I could get away with but nothing more.

What can I say? It’s much easier to head over to their website and either read about it there and/or download the beta whilst its active – go NOW!

So, after about a year of planning I flew out to join Dan and two of his third year students from Guild Hall School of Drama (London) in Helsinki. The first thing that hit me was the weather; it took your breath away it was that cold. I arrived about 11:30, after a beer I went straight to bed… but the next day we got up and went straight to the cabin.

THE CABIN

We had a porta-cabin upon which all the computer hardware was kept. (We where lucky as some people had tents!) And this was pretty much my view for the next 6 days…

Lots of coffee cups lying about!

AND IT BEGINS…

The first two days we had to set up, test and check the system. Then LUX was officially open and the public could all the pieces in full glory. Public viewing times where 4:00 PM until 10:00PM

We spent two days fine tuning and making the Isadora patch perfect. The sun went down about 3 so we had a short while to preview the images properly… this was from day one…

Day One

We attracted a lot of attention! So much so that people where blocking the pathway and filling up on the stairs in the image above!

People going about their daily business walking or cycling home had to stop and ask people to move out of the way. It was great to see so early on.

It became clear after only a few hours that children understood it straight away and some of the elder people took a little longer to figure out the concept and interaction. We found that a lot of people didn’t want to interact with the piece and just wanted to watch. But the flow of people made it work anyway. As people walked directly up to the cameras they soon realised that they where blocking the cameras and revealing more of the wall. We had a few dogs sniff the cameras and push buggies also looked good interacting with the wall images as they rolled by.

Some interesting observations for me including a guy swinging a white plastic bag around his head for about half an hour, a man and woman dancing like robots and a small child physically touching the wall and projected light thinking that it was somehow physically interactive.

The first night went really quick and some of the patches didn’t look as good as expected. But overall we where happy…. we then went for a beer and didn’t get home until 4 in the morning! The guys at sun effects looked after us and it was all networking (of course!).

So for the last 12 weeks I have been working as a Digital Creator at York Museums Trust. This has meant I have had to totally rethink the way in which I use and implement technology. I have not found any forums, Facebook pages or anything for us creative bunch of ‘Digital Creators’ and I feel a little bit on my own in this delicate but creative role. So I decided to use my blog and maybe people will find me along the way!

Forethought

In some areas of the museum and art gallery spaces there are already a lot of DVD players, TV monitors, projectors, etc that need turning on each morning and off again at night. The tour guides and volunteers already have enough to do of a morning so one important aspect to consider was the starting up and shutting down of the systems. Might sound quite simple… but not necessarily. How do you make sure that a computer is going to behave? Let’s discuss….

Hardware

We use Mac Mini (mostly) for the systems as they are small, quiet, cheap(ish) and have good overall performance. There are enough USB ports and most screens and projectors have HDMI/DVI-D now so its a good choice.

Configuring the OS (tame the lion!)
The first things I did when the machines came where:

Auto-Sign in. So that when a machine stats up there is no password. All of our machines are locked in secure spaces and are trackable anyway.

Disable all energy-saving features. We do not want the HD to go to sleep.

Turn off screen savers. (it might be ok to allow the screen saver now and again – up to you)

Change the wallpaper to something appropriate. Remove icons from off desktop so that if the system does crash then it doesn’t look a mess.

Disable all notifications (note: for Mountain Lion (10.8). This will show you how…[LINK] Even if you disable notifications manually in System Preferences the Apple Software update still show up. It can really get annoying.

Turn on restart if power cut. This is really handy for the rare occasion that a power cut may occur! Obviously.

Turn off all your software automatic updates. Go through all the menus in preferences to make sure!

If like me you are running the machine to power kiosk style interaction then you need to make sure that the software if going to keep running and running. Obviously testing is the best way to do this. Self testing is ok but you know the system and unconsciously are ‘nice’ to it. Ask a few people from various departments, ages, etc to try it out. Make sure everyone can work the system. See if any other problems occur.

But I decided to create something to make sure the software stayed live and even if the software did crash it would re-open within seconds, it’s all automated and can select precise files to open. I did this using automator (with the help of Mark Conilgio) and posted a link on the Isadora forum (this is the software I use for interactive AV design) The discussion can be found [HERE] You need a little bit of knowledge but if I can figure it out you sure can!

Auto Start/Auto Shut Down
Some of you will know what Apple Macs have a function that ‘Schedule’ the machine to turn off and on each day…

This can solve a big problem already… but what if you need something more advanced? Well I found a brilliant website called If This Then That, also known as IFTTT (I prefer the abbreviation!) And as you can see in this link for the Date & Time channel it can do quite a lot of stuff, and its web-based… BUT it works even better with a WiFi enabled plug! The Belkin Wemo Switch. The two companies have joined forces and API’s to allow each to talk to each other. So you can set the plug to turn on at 8:30 every morning and thus the machine will turn on. This saves energy and also works like a normal plug. [I must warn you at this point that we have had issues with the plug and our WiFi, it works best with ‘normal’ home WiFi and not advanced ultra secure networks like ours at the trust!]

There are other softwares and techniques but for now… the above should help some of you. Next…

How to check it all systems are online?
I can’t walk around all the various sites each morning to check to see if all the machines have turned on and are running. Of course I can ring and ask each site but not very efficient. So I decided to automate something that would let me know. The keyword here is automate and the little app called Automator on Mac is a godsend. I created an app that you can add to your log in items (more detail here) so that as each machine starts up it can either; run a quick and basic terminal command and save it to a drop box folder. So each morning I have a Dropbox folder which I can glance over and see that I have a new system report for each machine (including other system details such as RAM, wi-fi, etc) and if I do not have a report for machine…. then I can investigate! You can change this to take screenshots or anything you fancy really. Oh; and type “last” into terminal for a basic idea of the info I get.

Using my good friend IFTTT (look above if you don’t know what that stands for!) Dropbox is also useable; so a file added to Dropbox can A)email me B)tweet me c)SMS text me D)anything else I can think of that is IFTTT activated! It’s really neat.

So, By 9:00 every morning I already know that my machines are turned on and running. If not I get straight off the train and go and investigate. Most of the time the Internet is down and it just hasn’t synced the file in Dropbox.

I know people will say just use VNC and log into each machine but I really don’t have the time and this was it automatic and I can do it on the train via my iPhone or iPad. I set up a bog standard but hidden twitter account and it tweets my personal twitter account once each file from each machine has loaded before I even get to work. Depending on my 3G signal I receive all the tweets at the same time within a 10 minute period; again its simple and effective.

Final thoughts

Once the system is working then hold off for as looooooooooooooong as you can before updating. If it ain’t broke dont fix it! Even a simple update might change a file or directory that handles video, images, audio, etc. it might take you hours or even weeks to figure it out and that means a lot of down time for the system.

Keep a back up and save it in two or three places. The software files and media need to be backed up. it’s boring but do it! If files are small then email them to yourself or buy a cheap USB hard drive and drop them on there. Put it in a draw and forget about it – hopefully you wont need it.

I would really like to get some dialogue going between other AV creators in this sector. Please drop me a message!

UPDATE JUNE 2015

I have decided to re-visit this post. Two years on and the apple mac’s are still going strong. I had a few teething problems but all went well. My first issue was internet – the Wifi was not strong enough to cope so I do not use IFTTT now. I just have to live and hope! But; I will leave it in my blog as it’s handy for others.

I also use a lot of apple scripts now. I found that they are handy for automating tasks. I then export all scripts and automator workflows as apps and put them in login/start up. Here is a basic one I use to quit all apps and then just open my Isadora patch.

Once you get into Automator it’s really handy! it can run terminal commands and all sorts.
